Can I use my own SMTP server with Thunderbird?

Hi,

I was wondering that if its possible to send mail using my own localhost
mail server, I guess I made the settings using yast2. I am not sure that
I did right setup. And if I did setup my mail server corretctly, how can
I make thunderbird to use it? Any ideas?

You should be able to do that by just configuring “localhost” as the smtp server in thunderbird.
